JAIPUR: Mumbai Indians coach John Wright feels it's important for the players to control their aggression on the field. The T20 league has already seen the Virat Kohli-Gautam Gambhir spat, followed by reopening of 'Slapgate' wounds. And, both the incidents have left Wright dismayed.

"There's always a line to walk. Many people are watching the game and the players must be responsible," Wright said.

Also agreeing that the attitude of players have changed over the years, Wright said: "There wasn't much scrutiny about players' behaviour 20 years back, but now one needs to be careful."
